  • Publication number: 20190046426
    Abstract: A pro-fragrance composition includes a cucurbituril in complex with a fragrance molecule and use of the compositions in counteracting malodour. The cucurbituril is present as a mixture, wherein the mixture includes at least two different cucurbiturils selected from CB[5], CB[6], CB[7] and CB[8]. The complexed fragrance molecule is released when the composition is exposed to a stimulus. Also provides methods for the preparation of pro-fragrance complexes of cucurbiturils and fragrance molecules.

  • Patent number: 10189955
    Abstract: A nested capsule having a first capsule held within a second capsule. Each of the first and second capsules has a shell that is a supramolecular cross-linked network, such as a cucurbituril supramolecular cross-linked network. Each capsule shell is obtained or is obtainable from the complexation of a composition including a host, such as cucurbituril, and one or more building blocks having suitable guest functionality for the host, thereby to form a supramolecular cross-linked network. The nested capsules are suitable for delivering and selectively releasing an encapsulant at a location.

  • Publication number: 20180339078
    Abstract: The use of compositions including two or more cucurbiturils in counteracting malodour in a moist environment. The two or more cucurbiturils are selected from CB[5], CB [6], CB [7] and CB[8]. Also provided is a method for counteracting malodour in a moist environment, including application of a composition including a mixture of two or more cucurbiturils selected from CB[5], CB[6], CB[7] and CB[8].

  • Patent number: 10073037
    Abstract: The invention relates to the use of a construct for the detection of an analyte using surface enhanced spectroscopic techniques. The construct includes linked surfaces, where the link is formed by a linker providing a fixed inter-surface separation between the linked surfaces, wherein the linker is a linking compound, and at least one of the surfaces is the surface of a nanoparticle. The linking compound is suitable for interacting with the analyte. The linking compound may be a cucurbituril. The surface enhanced spectroscopic technique may be surface enhanced Raman spectroscopy (SERS).

  • Publication number: 20170028374
    Abstract: Provided is a capsule having a shell of material that is a supramolecular cross-linked network. The network is formed from a host-guest complexation of cucurbituril (the host) and one or more building blocks comprising suitable guest functionality. The complex non-covalently crosslinks the building block and/or non-covalently links the building block to another building block thereby forming the supramolecular cross-linked network. The capsules are obtained or obtainable by the complexation of a composition comprising cucurbituril and one or more building blocks having suitable cucurbituril guest functionality thereby to form a supramolecular cross-linked network.
